Etymology
From Middle English gilt, gult, from Old English gylt (“guilt, sin, offense, crime, fault”), of obscure origin. Possibly related with Old English ġieldan (“to pay, requite, punish”) (whence yield), from Proto-West Germanic *guldijā (whence Middle High German gülte (“debt, fee, financial duty”), Middle Low German gülde, German Gülte), from Proto-West Germanic *geldan (“to pay for”), from Proto-Germanic *geldaną (“to pay”). However, neither the Old English stem form nor its ending -t (instead of -d) fit the continental form.
